Hi, I want to know something about this variables, "quant4_mf" and "quant8_mf", which are defined in 'common.h' file line263, does the "quant4_mf" variable contain the value of quantized DCT coefficients of a macroblock or not? and what about "quant8_mf"? I will appreciate some one who can tell me it. Thanks & Regards, Hoda Roodaki,
